The ancient Mainsynagogue was the religious centre of the Jewish community of Segovia in medieval times. Located between Juderia Vieja street and the wall, it ran parallel to Puerta del Sol street. The current entrance was via Corpus Christi square, crossing a typical Segovian yard which forms part of the Convent of the Order of St. Clare, the owners of the temple.

The orientation of the Main synagogue in Segovia suggests, according to some authors, that it could have been erected on a previous mosque. With documentary evidence of its existence going back to 1373, it is known that it served as a Jewish temple until its confiscation en 1410 and that nine years later it had already been consecrated to Christian worship.

After terrible fire of 1899 which reduced the building to its structural lines, at the start of the last decade Segovia city council carried out the restoration of all the plasterwork, stained glass and chapters forming the original ornamentation by means of the original photos of the day of the fire in 1889 which were available and the remains conserved of the plasterwork originals.The artists involved were José María García Moro (Sculptor), José Luis Silveira (Restorer), Carlos Muñoz de Pablos (Stained glass designer) and Valero Herrera Ontañón (Municipal Surveyor).
